I am a 40 year old male, no smoke or drink. Over the last year I have noticed a lump on the back right side of my tongue where the throat starts. I thought perhaps it was from my tongue rubbing against my last molar on that side. It got worse over the last two months so I went straight to the ENT. He was very concerned and wanted to take a biopsy and sent me in for a CT scan. 4 days later I went back to the ENT who told me the biopsy was negative for cancer and the CT scan was pretty unremarkable. No lymph node swelling and no sign of tumor. He did say however that he did notice something on the left side of my tongue on the CT scan that looked more like what he would of expected to see on the right side. But after a thorough visually inspection and another look from his colleague, he was pretty certain there was nothing on the left side. After breathing a sigh of relief, the ENT still had concerns. He told me to stick out my tongue and then informed me it was coming out slightly sideways, usually the characteristic of something pressing on my hypoglossal nerve in the base of the tongue. Because of this, he did a much more extensive biopsy on the right side where the lump/sore is. He got as deep as the muscles in my tongue. Now, the results have come back and this time they are positive for Squamous Cell Carcinoma, non-invasive, moderately differentiated...positive for p-16. I am very confused as there seems to be a lot of conflicting information. He is transferring my case to the Stanford Medical Clinic where I hope to get a bit more clarity. He was pretty confident that the tumor was confined to that area only as the CT scan was negative and there were no swollen nodes or any other complications. He visually estimated the lump to be close to 2cm. Any thoughts on this would be greatly appreciated---thx
